AW: [Qgis-developer] Node tool

[Düster Horst]

I found a bug, which leeds to crash QGIS when using the merge tool under special circumstances. 
 
1. open a polygon layer 
2. toggle editing 
3. select 2 adjacent polgons 
4. activate "node tool"  
5. double click the common border of the two polygons => red squares arises 
6. select tool "merge selected features" and merge the two polygons => although the common border was removed, the red squares are still there 
7. click on a red square => QGIS crashes 
 
The new option "do not show vertex marker" is very nice, but when you have loaded many layers, you do not see or know if one or more layers are toggled in editing mode. In minimum the editing layers should be marked as "in editing mode" in the layer list. In former versions, until 0.8 I believe, the layer in editing mode were marked with a hashed box around the layer name.

Betreff: [Qgis-developer] Node tool 
 
Hi all, 
 
I've just added a new "node" tool for more rapid vector editing to svn 
trunk (r10890). It has been developed as a part of qgis-mapper 
project. 
 
It resembles a tool for editing paths by nodes that is present in 
every vector editor. How does it work (in QGIS): 
- click on a feature, its nodes will be marked by small rectangles 
- clicking and dragging a node moves it 
- double clicking a segment will add a new node 
- pressing delete key will remove active node 
- it's possible to select more active nodes at once: by clicking and 
dragging a rectangle 
- it's possible to select segment's adjacent nodes by clicking on the segment 
- it's possible to add/remove active nodes by using Ctrl when clicking 
a node or dragging a rectangle 
 
I recommend everyone to turn off vertex markers in options when 
working with this tool: the redraws are much faster and the map is not 
cluttered with markers. 
 
Please give it a try and as always we'll be happy to hear some feedback :-) 
 
Martin
